Název v původním jazyce

The influence of preformed plasma on a laser-driven shock produced in a planar target at the conditions relevant to shock ignition

Popis výsledku v původním jazyce

The effect of preformed plasma on a laser-driven shock produced in a planar target at the conditions relevant to the shock ignition scenario of ICF was investigated at the kilojoule PALS laser facility. Characteristics of the preformed plasma were controlled by the delay between the auxiliary and the main beam, and characterized using 3-frame interferometry, ion diagnostics, X-ray spectroscopy and K? imaging. Parameters of the shock produced in a CH(Cl) target by the intense laser pulse with energy ranging between 50 J and 200 J were determined by measuring the craters produced by the shock in a massive Cu target behind the layer of plastic. The volume and the shape of these craters was found to depend rather weakly on the preplasma thickness. From thecomparison of the measured crater parameters with those obtained in 2D simulations using the PALE code, it was estimated that the pressure at the rear (non-irradiated) side of the plastic layer reaches about 100 Mbar.
